My 2012 Infiniti QX56 has a loud rattling noise coming from the engine. This started around Oct 2020 and comes and go. It has got worse over the last month or so and has started stalling and acting like it doesn't want to go. A few times the car will start shaking while I'm driving. It has been checked out and codes for converter and timing chain are there. Engine light is on. I drive this car with my 2 children and am afraid of the safety issue. I know there is numerous others having these same 2 issues with my year and make of car. Spoke with Infiniti Corp. and they will not do anything about it because my VIN is not under the recall. However, the vehicles with this issue that have been repaired under the recall have the same engine and same issues that I'm having. I think all vehicles in 2012 regardless of VIN should be under the recall as I'm seeing so many with these issues.
My vehicle stalling all time which is very dangerous especially when I m driving on highway . More than 10 times I almost crash my vehicle.

Engine and engine cooling
- What is wrong
- Nissan is recalling certain model year 2004-2006 armada, titan, infiniti qx56 and model year 2005-2006 frontier, pathfinder and xterra vehicles. The intelligent power distribution module (ipdm) assembly contains an engine control module (ECM) relay that has a diode for electrical current noise reduction. The ECM relay may allow silicon vapor to form and, over time, the silicon evaporates from the diode molding which causes silicon oxide to develop on the ECM relay contact due to arcing.
- Risk
- This could cause engine stalling increasing the risk of a crash.
- Remedy
- Dealers will replace the ECM relay inside the ipdm assembly. This service will be performed free of charge. The safety recall began on december 6, 2010. Owners may contact nissan at 1‑800‑647‑7261.
